how to enable audio as root ?

[sean darcy]

I want to have sound when logged in as root. I don't care if it's a good 
idea or not.

And I don't care if it's pulseaudio or alsa, or whatever.

I've tried pulseaudio -D, but the volume control never can connect to 
the daemon. It just spams syslog with:
pulseaudio[6288]: Denied access to client with invalid authentication data.

I've added system-instance = yes to /etc/pulse/daemon.conf.

I've read 
http://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/SystemWide/ 
.

I've set up the users and groups as described.

.esd_auth exists in /var/run/puls

Does anyone have audio working as root?
